Doccol has been serving the stroke research field by providing MCAO sutures (silicone rubber-coated monofilaments) since 2004. Our delicate silicone rubber-coated monofilaments are specially designed and manufactured for inducing the intraluminal filament model of middle cerebral artery occlusion (MCAO), which has been widely used for in vivo experimental stroke studies. Using Doccol MCAO sutures for inducing stroke models will improve your model quality by reducing the occurrence of both the incomplete occlusion and the intracranial bleeding. With Doccol MCAO sutures, you will be able to achieve a highly consistent infarct as well as a low mortality rate. In addition to the super product quality, Doccol provides MCAO sutures with a great variety that was designed to meet the diverse demand from stroke investigators. For many years our MCAO sutures have been preferably selected by stroke investigators for inducing stroke models. We are proud to say that our clients are top-ranked universities, highly prestigious research institutes, and world-leading pharmaceutical companies from the United States, Canada, most European countries, Australia, Japan, South Korea, and India. Using Doccol MCAO sutures for inducing MCAO models has been reported to be able to reduce the standard deviation to 5% of its corresponding mean value as for infarction volume; and this modeling method is becoming a new standard for ensuring the highest quality of MCAO models. For more information please read Doccol Made a Difference in Stroke Modeling.
